Normal fault, Somerset

A normal fault is one where the rocks above the fault surface have slipped down-wards. The pale limestone bands at the cliff foot in the foreground have been faulted down below beach level in the block that forms the headland.

The rocks seen in the photograph are mudstones (dark) and limestones (pale) with fossils that show they were laid down on a Jurassic sea floor about 200 million years ago. There are many fossil sea shells, including ammonites (ancient relations of the squid family with beautiful coiled shells), and rare remains of fish and marine reptiles.
